The PSLV is a four-stage engine expendable rocket
with alternating solid and liquid fuel.
"That way, the reusable first stage is an important step to reduce cost compared to a 'classical' expendable rocket
, but I'm sure it is not the last step towards a fully reusable system."
The project would have created the world's first reusable "space plane", with the cost of development '20 to 30 times cheaper' than the expendable rocket
systems in use that eventually put man on the moon in 1969.
One reason why rockets cost so much is that over 90% of a rocket's weight is fuel and expendable rocket
Launched from an expendable rocket
, this delta-wing vehicle would use hypersonic lift to bounce off the atmosphere to lose speed before re-entry and its glide to a landing.
With expendable rocket
launchers in common usage, it behooves EVERY squadron to take a real close look at their doctrine to make sure this NEVER happens again!
He specifically encouraged researchers to think about building a new, small space telescope that could be launched on an expendable rocket
Jiro Kochiyama, NASDA's project manager who was involved in the HOPE program, said some people thought an ''extension of an expendable rocket
cannot transport humans.''
Another small, expendable rocket
, developed by Lockheed Martin Missiles and Space in Sunnyvale, Calif., has had one failure and is still undergoing testing.
The new space transportation system in conjunction with expendable rocket
boosters and continuously operating manned orbital complexes makes it possible to concentrate primary efforts on those trends in the conquest of space that will provide the maximum economic return to the national economy."
Virgin Orbit is also making progress on its own expendable rocket
. Rather than launch from the ground, the companys LauncherOne will be carried to a high altitude by a carrier aircraft before the rocket separates and carries its payloads into low-Earth orbit.
As stated earlier, I believe that this country is well placed to break the mould of conventional thinking, as it has no major commitments to expendable rocket
